I think if they did one that was the same, but maybe 1/3 the height, that would look great and let them keep using their investment in the manufacturing process.
I actually expect them to compensate by going more in the other direction.... potentially going back to a top configuration of dual Xeon processors with room for multiple high-end graphics cards. I don't expect them to have slots for Hard Drives, but multiple bays for U.2 SSD drives etc.
